The Playground is your interactive environment for testing agent prompts and configurations on real devices. Use it to iterate quickly on your automation logic without writing code.

​
Overview

The Playground allows you to:
  • Test agent prompts in real-time
  • Observe how your agent interacts with the device
  • Iterate on prompt wording and task instructions
  • Validate automation flows before production deployment

​
Selecting a Device

Before running a task, select a device from your account — a Personal Phone, Cloud Phone, or Physical Phone.
Not sure which device type to use? See the Device Types documentation to understand the differences between Personal Phones, Cloud Phones, and Physical Phones.

​
Running a Task

  1. Select your device from the device dropdown
  2. Enter your prompt describing what the agent should do
  3. Click Run to start the task
  4. Observe the agent’s actions in the device stream
The agent will interpret your prompt and execute the corresponding actions on the device. You can watch the device screen update in real-time as the agent performs each step.

Prompt Optimization

The Playground is designed for rapid prompt iteration. Use it to:

​
Writing Effective Prompts

Good prompts are specific and action-oriented. Here are some guidelines: Be explicit about the goal
Include context when needed
Break down complex tasks

​
Session Management

Each Playground session maintains state until you end it or switch devices:
  • App installations persist within the session
  • Login states are maintained
  • Files created during the session remain accessible
